>"An experiment began when a subject was shown the code “41234” on a screen and asked to type it out as many times as possible for 10 seconds and then take a 10 second break.

It's testing short term memory, maybe. 10 seconds on 10 seconds off to test your ability to memorize a string of numbers and type them out isn't the same thing as testing a skill.
